Detailed Description

a subclass of vtkProp3DFollower that ensures that data is always parallel to the axis defined by a vtkAxisActor.

vtkProp3DAxisFollower is a subclass of vtkProp3DFollower that always follows its specified axis. More specifically it will not change its position or scale, but it will continually update its orientation so that it is aligned with the axis and facing at angle to the camera to provide maximum visibilty. This is typically used for text labels for 3d plots.
